But despite the Yanomami’s appeals, many miners continue to operate on their land, destroying the forest and polluting the rivers with mercury. The uncontacted Yanomami are particularly vulnerable to the diseases transmitted by the miners.

Last month the Yanomami protested over the lack of medicines and health care, forcing the Ministry of Health to change the official in charge of indigenous health care in Roraima state.

Illegal gold-mining is destroying the Indians' forest, and polluting their rivers with mercury.

Last year, several groups of miners were removed from Yanomami land, but hundreds more remain, putting the Indians’ lives at risk.

A draft bill currently being debated could permit large-scale mining on indigenous land and bring further destruction. There over 650 requests from mining corporations to mine in the Yanomami territory.

Yanomami shaman Davi Kopenawa said, ‘This will not bring anything good for the Indians. It will only bring many problems, many diseases, and many bad people who kill Indians’.

Survival played a key role in bringing about the demarcation of the Yanomami’s land in 1992, and is now calling on Brazil to remove all the illegal miners once and for all, and to scrap the mining bill.
